What is the common factor of 16 and 20?
The factors of 16 are 1, 2, 4, 8, and 16. The factors of 20 are 1, 2, 4, 5, 10, and 20. The largest of the factors they have in common is 4, so 4 is the greatest common factor. Using prime factorization: The prime factors of 16 are 2, 2, 2, and 2. The prime factors of 20 are 2, 2, and 5. The prime factors in common are 2 and 2, so the greatest common factor is 2 x 2 = 4.
What is the HCF of 20 16?
To find the hcf, first split the numbers into their prime factors: 20 = 2x2x5 16 = 2x2x2x2 The next step is to identify any common prime factors. In this case both numbers have 2 and 2 as prime factors. Multiply these together and you get 4. Thus the hcf of 20 and 16 is 4.
